Hyperbaric oxygen therapy for iatrogenic arterial gas embolism after CT-guided lung biopsy : A case report.
This article reports on a case of a 74-year-old male patient who underwent computed tomography (CT)-guided lung biopsy of suspect nodules after squamous cell carcinoma of the tonsils. During puncture, sudden cardiovascular arrest occurred. The CT scan documented severe arterial gas embolism in the aorta, spinal canal, left heart ventricle, and brain. The patient was then transferred to our hospital for HBOT. After the first HBOT, an additional CT scan showed regression of all gas inclusions. In the treatment of gas embolism, HBOT is considered the gold standard and is indispensable. It is primarily used to reduce acute bubble effects and to avoid secondary bubble effects. Unfortunately, the long persisting gas occlusions and perfusion deficits led to severe hypoxic brain damage and a poor prognosis for the patient. In this case report we present the management of (iatrogenic) arterial gas embolism and point out the necessity of immediate HBOT. Furthermore, we discuss the pathophysiology leading to arterial gas embolism on the basis of the gas laws. PMID: 31264050 [PubMed - as supplied by publisher]
Conclusion: Due to the limited width of the SPC muscle, a margin in excess of 2 mm may not be attainable in a transoral radical tonsillectomy. Margin status may be ideally determined by the integrity of the SPC muscle in future oncologic studies, rather than an adequate distance measurement.ORL
Rationale: Many previous studies have investigated the necessity of routine histopathological analysis of tonsillectomy specimen, and most recent studies have suggested that such an analysis is not justified in asymptomatic patients or those with no risk factors for malignancy. Patient concerns: A 59-year-old man diagnosed with obstructive sleep apnea underwent surgery, including tonsillectomy; a tonsil specimen was sent to the department of pathology. Diagnosis: Although the patient did not exhibit any tonsil-related signs or symptoms, nor did the appearance of the tonsil appear to be pathological, the right tonsi...
ConclusionPlatinum analogs and taxanes were highly prescribed chemotherapy agents as they are highly effective in HNSCC. To prevent chemotherapy-induced cytotoxicity, supportive care agents, such as anti-emetics, proton pump inhibitors, anti-infective agents, and colony-stimulating factors, were used along with miscellaneous supplements.
In this study, we report the first-ever clinically occult OPC in an asymptomatic patient discovered through a saliva test. This case relied upon serial measurements of HPV-16 DNA in saliva, which fell to undetectable levels following low morbidity, curative treatment.
Management of contralateral tonsils with abnormal 18F-FDG PET/CT avidity in p16-positive oropharyngeal SCC is unclear. Definitive diagnosis requires diagnostic tonsillectomy of the FDG-avid tonsil. We aimed to evaluate the SUV uptake and radiation dose received by the contralateral tonsil in patients treated with definitive chemoradiation when the contralateral neck is electively treated.
ConclusionThis study evaluated the survival impact of HPV infection in LSCC patients. The OS of the HPV ‐positive group was better than that of the HPV‐negative group in terms of short‐term survival. Compared with the HPV‐negative group, the HPV‐positive group had a better trend of DFS, suggesting that a larger sample size and further exploration of the pathology and local control of HPV‐p ositive tumors are needed.
Rationale: Human papillomavirus (HPV)-related oropharyngeal cancer is becoming more common, the primary cancer AQ4 usually occult and appearing only as cystic cervical lymph node (LN) metastasis. Distinguishing between a benign cystic lesion and cystic LN metastasis is challenging given their similar radiologic and histologic appearances. Patient concerns: A 54-year-old man presented with a bulging cystic mass measuring 6.4cm on the right side of neck. Diagnoses: Postexcision diagnosis was second branchial cleft cyst. After 2 years, the cystic mass recurred, and HPV-related tonsillar squamous cell carcinoma with cy...
ConclusionsThe combination of belinostat 2000 mg/m2 days 1 –5 and 13-cRA 100 mg/m2 days 1 –14, every 21 days, was well-tolerated and an MTD was not reached despite doubling the established single-agent MTD of belinostat.
AbstractBasaloid squamous cell carcinoma (BSCC) is a variant of oral squamous cell carcinoma, is an aggressive, high grade variant and rare subtype of the head and neck SCC that less common in tonsils. Here, we are reporting a case of BSCC involving the tonsil with an extension on the cervical lymph node region.
In this study, we performed immunohistochemical analysis using a rabbit anti-DGKζ monoclonal antibody (mAb) (clone EPR22040-80) against tissues from the tonsils of a patient with oropharyngeal squamous cell carcinoma. We demonstrated that many DGKζ-expressing T cells are localized in the tonsils. We further characterized the binding epitope using an enzyme-linked immunosorbent assay and found that Pro790, Gln791, Gly792, and Leu795 residues of DGKζ are important for facilitating anti-DGKζ mAb binding to DGKζ. This anti-DGKζ mAb could be valuable in immunohistochemical analyses in determining t...
